# Enterprise Database Query Plan Optimization & Remediation Traces (Community Preview)

<p align="center">

</p>

## Overview
High-concurrency database workloads frequently degrade due to optimizer plan misestimations, unindexed correlated joins, merge-sort memory spills, and non-sargable expressions.

This repository hosts the **Community Preview (250 verified traces)** of an architectural fine-tuning dataset spanning **PostgreSQL 16, MySQL 8.0, ClickHouse 24, CockroachDB, MariaDB, and SQLite**. Each record pairs an authentic production query regression and raw execution plan (`EXPLAIN ANALYZE`) with chain-of-thought architectural diagnosis, actionable remediation DDL, and dialect-compliant optimized queries.

## Data Structure & Schema

```json
{
  "database_engine": "string",
  "slow_query": "string",
  "execution_plan": "string",
  "diagnostic_thought": "string",
  "remediation_ddl": "string",
  "optimized_query": "string"
}
```

### Field Definitions

| Field | Data Type | Description |
| :--- | :--- | :--- |
| `database_engine` | `string` | Target engine dialect & exact version (e.g., `PostgreSQL 16.2`, `ClickHouse 24.3`). |
| `slow_query` | `string` | Realistic unoptimized SQL query triggering runtime performance degradation. |
| `execution_plan` | `string` | Raw optimizer output (`EXPLAIN (ANALYZE, BUFFERS)` or JSON plan) exposing node bottlenecks. |
| `diagnostic_thought` | `string` | Step-by-step reasoning diagnosing node cost, row estimate deltas, and I/O buffer behavior. |
| `remediation_ddl` | `string` | Executable DDL statements (`CREATE INDEX CONCURRENTLY`, table parameter tuning). |
| `optimized_query` | `string` | Performant rewritten query strictly adhering to engine dialect grammar. |

## Quickstart (Hugging Face Datasets)

```python
from datasets import load_dataset

# Load Community Preview
dataset = load_dataset("ayushjoshi2012/sql-optimization-diagnostic-traces", split="train")

# Inspect a single diagnostic trace
sample = dataset[0]
print(f"Engine: {sample['database_engine']}")
print(f"Slow Query:\n{sample['slow_query']}")
print(f"Diagnosis:\n{sample['diagnostic_thought']}")
print(f"Remediation DDL:\n{sample['remediation_ddl']}")
print(f"Rewritten Query:\n{sample['optimized_query']}")
```

## Core Domain Taxonomy

Traces are generated across representative enterprise schema designs:
* **Fintech & Ledger Core:** Double-entry ledger scans, implicit UUID-to-integer type coercion, balance aggregations.
* **IoT & Telematics:** Granule skip-index mismatches, partition decompression stalls, time-bucket groupings.
* **B2B SaaS & Security:** High-offset tenant audit logs, soft-delete booleans, unindexed RBAC joins.
* **Healthcare & EHR:** Unindexed composite foreign keys, leading-wildcard text filters, outdated optimizer statistics.
* **Freight & Global Logistics:** Disk-spilling merge joins on departure timestamps, Cartesian row multiplication.
* **AdTech & Gaming Telemetry:** Unindexed streaming click joins, unbounded window function sorts, leaderboard lock contention.
